Booking Korea, in English.
Booking Korean dive shops runs overwhelmingly on phone + KakaoTalk. Across the 81 shops in the dataset, phone is 96% and Kakao about 49%, while the paths that let foreigners complete a pre-booking in English with an overseas card are very few. The biggest friction point for inbound isn't the diving itself — it's the booking flow.
The booking flow is the biggest friction
Korean dive shops are built around a domestic phone + KakaoTalk workflow. The default channel is a Korean-language phone line that's hard for foreigners to use on their own. Before arrival, there are effectively only three English pre-booking paths.
- Native English OTA: Ulleungdo Hakpo Dive Resort (Klook)
- Own English websites: Jeju Big Blue 33 · Bada Dive
- The rest of the ‘platforms’ are Korean-language OTAs (MyRealTrip, WAUG, Yanolja, etc.)
81 shops, tallied by channel
Multiple channels counted per shop. Jeju is the most digitized (highest share of web, Kakao, and platforms), while the East Sea relies most heavily on phone.
